Plants without conspicuous rhizomes. Culms 17-75(-90) cm, 2-3.5 mm wide basally, 0.5 mm wide distally. Leaves: sheaths tight, green, fronts hyaline; ligules to 2.5 mm, as long as wide; widest leaf blades 2.2-4.6 mm wide, papillose adaxially. Inflorescences with 5-14 spikes, 1.4-2.8 cm × 9-14.5 mm; proximal bracts 0.7-6(-10) cm, shorter than to 2.5(-5) times as long as inflorescences; spikes with (2-)4-24 ascending to spreading perigynia; proximal internodes shorter than proximal spikes. Pistillate scales pale brown to greenish hyaline, with green usually 1-veined center, ovate, 1.6-3.1 × 1.4-2.2 mm, body narrower than and 2/3 length of perigynium, apex usually awned, awn to 3.6 mm. Anthers 1.3-1.9 mm. Perigynia pale green to pale brown, veinless or weakly 1-10-veined on each face, 3.3-5.6 × 1.9-2.8 mm, margins serrulate distally, base of body somewhat spongy, thickened; beak (1-)1.4-1.8 mm, apical teeth (0.5-)1.4-1.8 mm. Achenes suborbiculate, 1.8-2.8 × 1.5-2.2 mm. Fruiting spring. Open mesic forests and savannas; 200-500 m; Okla., Tex. Carex perdentata is fairly widespread in central Texas and may occur in similar habitats in neighboring states. It can be confused with other species in the section, especially C. arkansana, C. mesochorea, and C. muehlenbergii.

Carex

Texas Sedge (Carex texensis) is a low, clumping sedge that can reach about four inches tall by six inches wide per plant. Leaves are dark green in color, and should remain evergreen in all but the coldest areas of its natural range. Greenish-white flower stalks are produced in the spring. It can be used as a low-maintenance lawn replacement, needing only 2-3 mows per year to remain looking healthy. This sedge will grow best if given partial to full shade and is adaptable to any type of soil. Part of the attraction of the genus Carex, into which sedges fall, is its tremendous variety and adaptability. There are more than 2,000 species of Carex, and they are found in a wide range of habitats in nature. They vary from miniatures with foliage only 1 to 2 inches high, to specimens growing to 3 or 4 feet. Some creep, some clump, some do a little of both. They can be found in sun or shade, in wet soils or heavy clay, from coastal dunes to alpine scree. In almost every ecosystem, there is at least one sedge with good, lawnlike qualities.

I planted 400 Pennsylvania carex plugs in 2018 on a small slope leading down to our driveway through a mixed forest of pines and native trees in northeast Maryland. Attempting to stop trying to mow it and create a waving movement with the wind that comes blowing through. This past fall after cleaning up the long bed I applied weed preventer. The plants are coming up with no other maintenance. This year I see seed heads for the first time. Can I fertilize with lawn fertilizer? Your article was very helpful, however left me questioning if my plants are going to grow and spread or do I need to do something else to help them along.Hi, Marian: According to the Minnesota Extension Service, Carex muskingumensis tolerates shade and moist/wet conditions. It also recommends several alternatives. Ask nurseries in your area what performs well in your conditions and climate. The Minnesota Horticultural Society also is a good resource.
